Application June 15, 1954, Serial No. 436,762

1 Claim. (Cl. 240-54) The present invention relates to new and usefulimprovements in portable light guards, and has for its primary object toprovide, in a device of this character, comprising a rotatablyadjustable suspension hook, novel means for rmly but releasably securingsaid hook in adjusted position.

Another very important object of the invention is to provide a guard ofthe aforementioned character which may be expeditiously opened whenaccess to the interior is desired.

Other objects of the invention are to provide a portable light guard ofthe character described which will be comparatively simple inconstruction, strong, durable, highly eilicient and reliable in use,compact, light in weight, and which may be manufactured at low cost.

All of the foregoing and still further objects and advantages of theinvention will become apparent from a study of the followingspecification, taken in connection with the accompanying drawing whereinlike characters of reference designate corresponding parts throughoutthe several views, and wherein:

Figure 1 is a view in side elevation of a guard constructed inaccordance with the present invention mounted on a portable light;

Figure 2 is a view in vertical section through the invention;

Figure 3 is a detail View in vertical section, taken substantially onthe line 3 3 of Figure 2; and

Figure 4 is a detail view in perspective of the hook locking disc.

Referring now to the drawing in detail, it will be seen that referencecharacter 5 designates generally a con ventional portable light. Thelight 5 includes the usual handle 6 having mounted in its upper endportion a suitable socket 7 for the reception of an electric lamp 8. Aconductor cord 9 passes through the handle 6 to the socket 7.

The embodiment of the present invention which has been illustratedcomprises a shade or reflector 10 of suitable material and acomplemental wire cage 11. The reflector 10 is of a depth to enclose themajor portion of the lamp 8 and said reflector comprises, on its lowerend, a neck 12 which is mounted on the lower portion of the socket 7.

As shown to advantage in Figure 2 of the drawing, the upper end or top13 of the reilector 10 has formed there- 2,707,229 Patented Apr. 26,1955 rice in an opening 14 for the reception of a hook 15 on the upperend of the wire guard or cage 11. The lower end ot' the cage 11 isdetachably secured to 'the neck 12 of the reflector 10 by meanscomprising screws 16.

The top 13 of the reflector 10 has struck or pressed thereinto aninternal rib 17. Rising from the top 13 of the reflector 10 is asuspension hook 18 which passes slidably through the rib 17. A metallicdisc 19 is lixed on the lower end portion of the hook 18 As shown toadvantage in Figure 4 of the drawing, the disc 19 has formed thereinradial corrugations or grooves 20 for the reception of the rib 17.

The shank of the hook 18 passes slidably through a washer 21 which restson the top 13 of the reflector 10. Fixed on the shank of the hook 18 isring or collar 22. A coil spring 23 encircles the shank of the hook 18between the elements 21 and 22 for yieldirigly urging said hook upwardlyfor engaging the disc 19 with the rib 17 of the reector top 13.

It is thought that the manner in which the device is used will bereadily apparent from a consideration of the foregoing. Briefly, torotatably adjust the hook 18, said hook is depressed against the tensionof the coil spring 23 for disengaging the disc 19 from the rib 17. Thehook 18 is then turned to the desired position and released. When thehook 18 is released, said hook is elevated by the spring 23 for engagingthe disc 19 with the rib 17, said rib entering one of the corrugationsor grooves 20 in said disc. To detach the cage 11, the screws 16 areremoved, thus freeing the lower end of said cage. The cage is then swungoutwardly and upwardly in a manner to permit the hook 15 to bedisengaged from the opening 14.

It is believed that the many advantages of a portable light guardconstructed in accordance with the present invention will be readilyunderstood, and although a preferred embodiment of the device is asillustrated and described, it is to be understood that changes in thedetails of construction may be resorted to which will fall within thescope of the invention as claimed.

What is claimed as new is as follows:

A portable light guard comprising; a reflector including a top having arib therein, a rotatably adjustable suspension hook extending slidablythrough the rib, a disc fixed on the hook in the reflector and having aplurality of radial grooves therein for selectively receiving the rib, awasher slidable on the hook and resting on the top, a collar fixed onthe hook above the top, and a coil spring resting on the washer andengaged with the collar for yieldingly urging the hook upwardly forengaging the dise with the rib for securing said hook in rotatablyadjusted position.
